Abstract
An absorbent article comprising a topsheet, a backsheet joined to the topsheet, and an absorbent core positioned intermediate the topsheet and the backsheet and comprising a core absorbent material, in which the core absorbent material comprises superabsorbent polymers with a bio-based content from about 5% to about 100% using ASTM D6866-10, method B and the absorbent article comprises a polyolefin content of at least about 90% by weight, based on a total weight of the absorbent article excluding the core absorbent material.
Claims19
An absorbent article comprising:
- a topsheet;
- a backsheet joined to the topsheet and comprising one or more of a backsheet film or a backsheet nonwoven web;
- an absorbent core positioned intermediate the topsheet and the backsheet, the absorbent core comprising a core absorbent material;
- and
- one or more of a landing zone, a stretch ear film, a back ear nonwoven web, tape tabs, ear hooks, a front ear nonwoven web, a waist feature nonwoven web, waist feature elastics, a barrier leg cuff nonwoven web, outer leg elastics, an acquisition material, a core cover nonwoven web, chassis adhesives, or core adhesives;
- wherein the core absorbent material comprises superabsorbent polymers with a bio-based content from about 5% to about 100% using ASTM D6866-10, method B;
- wherein at least one of the topsheet or the backsheet and at least one of the backsheet film, the backsheet nonwoven web, the landing zone, the stretch ear film, the back ear nonwoven web, the tape tabs, the ear hooks, the front ear nonwoven web, the waist feature nonwoven web, the waist feature elastics, the barrier leg cuff nonwoven web, the outer leg elastics, the acquisition material, the core cover nonwoven web, the chassis adhesives, or the core adhesives comprise a bio-based polyolefin with:
- a bio-based content from 5% to 100% using ASTM D6866-10, method B;
- and
- a purity of about 98 weight % polyolefin and less than 2 weight % impurities;
- and
- wherein the absorbent article comprises a polyolefin content of at least about 90% by weight, based on a total weight of the absorbent article excluding the core absorbent material;
- and
- wherein recycled polyolefin recovered from an entirety of the absorbent article via a recycling operation comprises a polyolefin content of at least about 90% by weight, based on a total weight of the absorbent article excluding the core absorbent material.
